Abstract

The invention provides an offline playing method and apparatus of online encrypted slice videos based on an iOS operating system. A player needs to sends a request carrying a signature to a local server to play a local offline encrypted video, and the local server only provides local offline video resources to the player only when the signature is verified to be correct. The signature is generated by calculating user information. The operation of the user information is added in a decryption algorithm used by a downloader in a decryption process, so the offline video resources cannot be normally played if the user registration information is incomplete or incorrect, thereby reinforcing the security of the local offline video resources. The scheme abides by the HLS protocol, all resources used in the protocol are cached in the local, and the local server returns the local resources to the player by HTTP response, thereby consuming no traffic. The offline playing method and apparatus of the online encrypted slice videos based on the iOS operating system provided by the invention is safer and more convenient.

Description

A kind of offline player method of online encrypted slice video based on ios operating system and Device
